Fig. 7 illustrates the figure that CCE is distributed to the example of band system band.With reference to figure 7, a plurality of continuous CCE in logic are imported into interleaver.It is that unit mixes input CCE that this interleaver is done in order to REG.Therefore, form under the state of frequency/time resource in being dispersed in whole frequency/time-domain of a CCE and physically be distributed in the controlled area of subframe.Finally, although control channel be take CCE as unit forms, interweave and be take REG and carry out as unit, thereby maximize frequency diversity and interference randomization.
Fig. 8 is the figure that is illustrated in the structure of the uplink sub-frames used in the LTE system.
With reference to figure 8, uplink sub-frames can be divided into the physical uplink link sharing channel (PUSCH) that the physical uplink control channel (PUCCH) of carrying control information is assigned to the Qi De district and carries user data and be assigned to the Qi De district.The mid portion of subframe is assigned to PUSCH.In frequency domain, the two side portions of data field is assigned to PUCCH.The control information sent on PUCCH comprises the channel quality indication (CQI) of ACK/NACK for HARQ, indicating downlink downlink channel state, for the order indication (RI) of MIMO and as the dispatch request (SR) of uplink resource allocation request.Use a Resource Block of the different frequency of each time slot that occupies subframe for the PUCCH of a UE.That is to say, distribute to two Resource Block of PUCCH in time slot interface frequency hopping.Especially, Fig. 7 exemplarily illustrates and has PUCCH that m is 0, has PUCCH that m is 1, has the PUCCH that m is 2 and have the PUCCH that m is 3 and be assigned to subframe.
Hereinafter, will be described carrier aggregation technology.Fig. 9 is the concept map of diagram carrier aggregation technology.
Carrier aggregation refers to UE will comprise that a plurality of frequency chunks of uplink resource (or component carrier) and/or down-chain resource (or component carrier) or a plurality of (logic) community are used as large logic frequency band so that use the method for broad frequency band in wireless communication system.Hereinafter, will use for convenience of description term " component carrier ".
With reference to figure 9, the whole system band is the logical band with maximum bandwidth of 100MHz.The whole system band comprises five component carriers (CC), and each CC has the maximum bandwidth of 20MHz.CC comprises one or more physically continuous subcarriers.Although all CC have identical bandwidth in Fig. 9, this is only illustrative, and CC can have different bandwidth.In addition, although CC is shown in frequency domain as continuous, figure only illustrate logical concept and so CC may be physically continuous or separate.
Different centre frequencies can be used to CC or a convenience center frequency can be used to physically continuous CC.For example, in Fig. 9, based on all CC, are physically continuous supposition, can use centre frequency A.In addition, based on CC, not physically continuous supposition, centre frequency A, centre frequency B etc. can be for each CC.
In this manual, CC can be corresponding to the system band of Legacy System.By based on Legacy System, defining CC, can promote the UE of wherein evolution and leave over backwards compatibility and the system in the wireless communications environment that UE coexists.For example, the LTE-A system supports that in the situation of carrier aggregation, each CC can be corresponding to the system band of LTE system therein.In this case, CC can have be selected from 1.25,2.5,5,10 and the bandwidth of 20MHz among any one.
In the situation that the whole system band is expanded by carrier aggregation therein, for the frequency band of communicating by letter with each UE, with CC unit, defined.UE A can be used as the 100MHz of the bandwidth of whole system, and carrys out executive communication with all five CC.UE B 1To B 5Can be only by the bandwidth of 20MHz and each, with a CC, carry out executive communication.UE C 1And C 2Can and respectively with two CC, carry out executive communication by the bandwidth of 40MHz.Two CC may be continuous or discontinuous in logic/physically.UE C 1Use two discontinuous CC and UE C 2Use two continuous CC.
Although use a down link component carrier and a up link component carrier in the LTE system, can use some component carriers in the LTE-A system as shown in Figure 9.The scheme of the control channel of at this moment, data channel being dispatched can be divided into existing link carrier dispatching (linked carrier scheduling) scheme and existing across carrier dispatching (cross carrier scheduling) scheme.
More specifically, in link carrier dispatching scheme, the control channel sent via specific CC, via this specific CC data dispatching channel only, is similar to the existing LTE system of using single CC.
In across the carrier dispatching scheme, on the other hand, the data channel that the control channel scheduling of using carrier wave indication field (CIF) to send via main CC sends via main CC or another CC.
Figure 10 illustrates the figure of application across the example of carrier dispatching technology.Especially, in Figure 10, the number of distributing to the community (or component carrier) of via node is 3, and carries out across the carrier dispatching technology with CIF as above.Suppose that downlink cell (or component carrier) #A is that main down link component carrier (is main plot; PCell), and other component carrier be that component carrier #B and component carrier #C are auxiliary component carrier (Ji Fu communities; SCell).
Hereinafter, will be given in the signal transmission between UE and eNB in the wireless communication system of the carrier aggregation technology of having applied the unwarranted frequency band of use according to the present invention (unlicensed band) and the description of the method that receives.
The<the first embodiment >
At first, the predetermined preambles between eNB and UE is positioned in the situation of front end of each subframe therein, and UE can receive that this is leading to determine whether corresponding subframe is set up in up link or down link.
For example, leadingly be positioned at identical Energy Resources Service and comprise that having the information that minimum dimension is 1 bit arranges the direction (for example, up link or down link) of corresponding subframe with pointer to it in all subframes.ENB and UE carry out downlink communication or uplink communication according to the structure by leading determined subframe.
In addition, can decide enabling of unwarranted frequency band based on carrier sense (CS) operation.Above-describedly leadingly can indicate unwarranted frequency band in idle condition.In addition, can be only send therein this under the state of unwarranted frequency band in idle condition leading.
Figure 11 is the figure illustrated according to the structure of the ul transmissions process of first embodiment of the invention and uplink sub-frames for this reason.
With reference to Figure 11, the communication direction of corresponding subframe is set in the situation of up link therein, for protection part (guard section) or the guard time (G switched between transmission mode and receiving mode p) be located at leading after.For example, in guard time, UE can carry out the Rx-Tx switching and eNB can carry out the Rx-Tx switching.
In addition, UE must receive leading in next subframe.For this reason, for example, guard time for switching between transmission mode and receiving mode (, Tx-Rx switching) is located at the last of current subframe.Propagation delay (T therein p) in large situation, guard time can be extended and therefore can be located on some character positions.
Figure 12 is the figure illustrated according to the structure of the downlink transmission process of first embodiment of the invention and downlink subframe for this reason.
With reference to Figure 12, the communication direction of corresponding subframe is set in the situation of down link therein, and Rx-Tx switching is unwanted, be different from up link, but guard time can as uplink sub-frames, be positioned at leading after.At this moment, may not allow UE to send any signal in corresponding guard time.This structure similarly keeps the position of resource, is in transmission and the reception of log-on data in downlink subframe and uplink sub-frames in described position, makes UE can send or receive data under stationary state.
Figure 13 is the figure that the configuration of the subframe that the structure according to the subframe of use Figure 11 of first embodiment of the invention and 12 configures exemplarily is shown.
Next, Figure 14 is the figure illustrated according to the example of the execution uplink data transmission of first embodiment of the invention.Especially, Figure 14 illustrates UE at T pCarry out the example of uplink data transmission PUSCH transmission while being present between eNB and UE by the structure of the uplink sub-frames of Figure 11.
With reference to Figure 14, UE is by the confirmation of 1. uses of corresponding subframe after leading decoding->2.Rx-Tx switching->3. use sequential to shift to an earlier date T AThe order of uplink data transmission send uplink data.Especially, the T of Figure 13 AHave and T pIdentical value.Work as T A(=T p) be worth while increasing, the number that can be used to the symbol of uplink data transmission can relatively reduce.Above-described guard time (G p) can be used to T A.
In addition, eNB can look like to UE informing uplink data transmission period, and the other method in PUSCH transmission time is like that to UE notice sequential rollback (timing retreat) (T R) information.T RBe indication the past to lead time of reception to play the value that how long starts ul transmissions, and can be expressed as the number of symbol or chronomere.In addition, eNB can notify T to UE by high-level signaling more R, or can be to UE informing uplink license or down link control information under the state add specific fields to it, to send downlink allocation information.Alternatively, can consider to reuse field that (current) be not used or for the method for the code-point state of existing down link control information.
Therein for T RSpecific fields be added to down link control information with in the situation that sends downlink allocation information, the nearest downlink subframe before eNB can be performed down link control information uplink sub-frames from actual therein uplink data transmission send to UE.
In addition, the field that (current) is not used therein or code-point state are reused in the situation of existing down link control information, the T corresponding with this specific fields or this code-point state RCan be by realizing sharing corresponding table (or aggregate information) between eNB and UE in advance.
The<the second embodiment >
In the situation that use unwarranted frequency band based on the carrier sense operation in having applied the wireless communication system of carrier aggregation technology, eNB can be in advance by high-level signaling more to existence and the position of UE informing uplink subframe (or uplink sub-frames and downlink subframe).For example, eNB can have the part T(section T of constant length to the UE notice is relevant by high-level signaling more) during the effective information of the configuration of uplink/downlink subframe.
Hereinafter, for convenience of description, the information of the relevant configuration of effective uplink/downlink subframe during having the part T of constant length will be called as message X.
In addition, the predetermined value between eNB and UE can be used as the T value, or eNB can be by additional more high-level signaling, and message Y notifies the T value together with message X to UE.Can the specific period value based on predetermined come updating message X and message Y.In addition, message X(or message Y) can or be sent to UE by the downlink transmission in unwarranted frequency band from eNB by the down link principal component carrier wave in authorized frequency bands (licensed band).
In addition, when UE special time for example SF#a when eNB receives message X and message Y or only receive message X, between eNB and UE, mutually make the application start of message X put consistent method and can be considered to as following situation A) to C).
A) be selected from the particular sequence that can be used as among the leading sequence of N altogether and can be designated as homing sequence X, it can be used to the application starting point of notification message X.For example, at SF#b(wherein b >=a or b > a) locate from carrying out the communicating by letter based on unwarranted frequency band with eNB during eNB receives the part T of the message X of UE based on receiving at SF#a from SF#b of homing sequence X, and, during the further part T-1 except SF#b, UE can not expect to receive from eNB use leading of indication subframe.
Simultaneously, except use above-mentioned, the homing sequence X that is designated as the application starting point of notification message X can be used to notify the use of corresponding subframe, and corresponding subframe is uplink sub-frames or downlink subframe.
Figure 15 is the figure illustrated according to the example of the configuration of the application subframe of second embodiment of the invention.
With reference to Figure 15, the application A) technology, and the supposition T be the predetermined value of the 10ms between eNB and UE.In addition, the configuration of uplink/downlink subframe is used as [DDUUUDDDDD] by message X and sends with signal.After, light application message X from the time when receiving homing sequence X.
B) when UE special time for example SF#a receive message X and message Y or only during message X from eNB, the time when application message X practically can be defined as T Offset.T OffsetBy with time slot unit, express with subframe unit or with radio frame unit's (or with (reception) leading number).T OffsetCan be set to 1 or larger particular value.Predetermined value between eNB and UE can be used as T Offset, or eNB can for example, notify T together with message X to UE by additional more high-level signaling (, message Z) Offset.
T OffsetReference point can be designated as previous or next nearest time slot interface, comprise that SF#a(has received message X at this SF#a place), subframe interface or radio frame interface.This can preset between eNB and UE.Alternatively, T OffsetReference point can be designated as the first symbol of previous particular radio frame (such as the radio frame of SFN#0), comprise SF#a, received message X at this SF#a place.In addition, T OffsetCan be counted as the leading number received subsequently that comprises SF#a, at this SF#a place, receive message X.
Simultaneously, in the application from message X, the initial UE after part T of lighting does not over for example receive, for measuring the reference signal such as CRS of (, RSRQ, RSRP and RLM) from eNB not being desirably in unwarranted frequency band, and same, does not carry out and measures operation.
Figure 16 illustrates according to the UE of second embodiment of the invention to apply the initial figure that only for time period T, in the DL subframe configured by message X, carries out the example of measuring that lights from message X.Especially, in Figure 16, suppose that the uplink/downlink subframe is configured to [UDDUDDUDDD].
In Figure 16, the total number of supposing UE is 3.UE is carrying out and is measuring during part T from initial only the lighting of the application of message X in the downlink subframe configured by message X, and in other downlink subframe, is not to carry out and measure in invalid subframe.
When C) result of the operation of the carrier sense in determining unwarranted frequency band is idle duration " T_IDLE ", eNB(or UE) suppose and can in uplink communication or downlink communication, use corresponding unwarranted frequency band.
Figure 17 is the figure illustrated according to another example of the configuration of the application subframe of second embodiment of the invention.Suppose that the configuration of message X in Figure 17 and carrier sense operation identical with the configuration in Figure 15 is performed (time slot based on unwarranted frequency band (or subframe) interface) from initial the lighting of the second time slot.
With reference to Figure 17, eNB(or UE) result that can determine the carrier sense operation is the point of application that point that idle duration " T_IDLE " is positioned is set to message X.In addition, eNB(or UE) carrying out point that the carrier sense operation is positioned can scheduled justice or notify in addition by high-level signaling more.
The<the three embodiment >
Simultaneously, therein eNB by high-level signaling more, to the UE notice in the situation that effective message X during predetermined amount of time T, eNB can specify a part that is selected from the specific sub-frame among the some subframes that form message X to carry out the carrier sense operation.The part of specific sub-frame can be last the second time slot district in some subframes corresponding with predetermined amount of time T.ENB and UE are not used corresponding district in downlink communication and uplink communication.At this moment, consider that the symbol that reduces number can be by rate-matched or punching from the PDSCH/PUCSH of corresponding subframe transmission.
In addition, eNB(or UE) can be based in part T the carrier sense that only arranges with respect to unwarranted frequency band during being designated as the corresponding district that carries out the carrier sense operation of the uplink/downlink configuration supposition of repeatedly being applied from the first subframe of radio frame #0 operate.
Alternatively, a part that is designated as the specific sub-frame of carrying out the carrier sense operation can be set to have the symbolic component of rear half-size scale of the last symbol of the last subframe corresponding with part T.In this case, if UE must send SRS with the last symbol of corresponding last subframe, SRS only can be limited to make and send SRS with the first half symbolic component of last symbol.Only use the SRS that the first half symbolic component of last symbol sends can be called as " SRS that length reduces " or " SRS of shortening ".
In addition, when the part of specific sub-frame is designated as while carrying out the carrier sense operation, eNB can come together to notify the information about the position of the part of this specific sub-frame to UE together with message X by high-level signaling more or (the existing or new) specific fields by the down link control information that sends with signal via physical control channel.
A part that is designated as the specific sub-frame of carrying out carrier sense operation as above can be specified by the various units with such as time slot, subframe and symbol.Such information may be relevant information shared between eNB and UE, eNB can notify such information to UE by high-level signaling more, or eNB can notify such information to UE by (existing or new) specific fields of the down link control information that sends with signal via physical control channel.
For example, determining that last subframe that eNB is being assigned to the carrier sense operation is the result of carrying out the carrier sense operation with respect to unwarranted frequency band in the second time slot district of SF#n while being idle duration " T_IDLE ", eNB can be that SF# (n+1) is to SF# (n+T) at part T(from SF# (n+1)) during the unwarranted frequency band of use.The uplink/downlink subframe process of applying during part T from SF# (n+1) in configuration, can be in the situation that do not have eNB to use the existing configuration of uplink/downlink subframe to the new configuration of the change of UE informing uplink/downlink subframe by the more high-level signaling added.
In addition, determining that last subframe that eNB is being assigned to the carrier sense operation is the result of carrying out the carrier sense operation with respect to unwarranted frequency band in the second time slot district of SF#n while being busy (BUSY), eNB can be that SF# (n+1) is to SF# (n+T) at part T(from SF# (n+1)) during do not use unwarranted frequency band.ENB does not carry out uplink communication and downlink communication during part T, at unwarranted frequency band during described part T, is not used and can in the remaining area except the designated district that carries out carrier sense operation, even carry out the carrier sense operation.ENB can not use the various values except T to arrange with the time of unwarranted frequency band, and eNB can by the specific fields of physical control channel or more high-level signaling notify corresponding value to UE.For example, if eNB notifies corresponding value by high-level signaling more to UE, this corresponding value can be sent out together with message X.
In addition, eNB can be used the maximum times (T_max) of the configuration of the uplink/downlink subframe in part T to each UE or each UE notice of being set to particular group by high-level signaling more.In one embodiment, when the configuration of the uplink/downlink subframe in part T is used, for each UE or each UE(, be set to particular group) the T_max value can reduce 1.At eNB in the situation that the UE(of the configuration of uplink/downlink subframe or each UE of particular group in special time choice for use part T), priority can be there is to the UE of relatively high T_max value.In addition, can upgrade each UE for each UE(or particular group based on the predetermined period value) the T_max value.
Figure 18 illustrates the figure with the example of carrying out the carrier sense operation according to the configuration given zone of third embodiment of the invention.Especially, in Figure 18, suppose that the uplink/downlink subframe of message X is configured to [DDDUDUDDDD].
With reference to Figure 18, the predetermined value between eNB and UE is used as T.In the figure, T is set to 10ms, i.e. a radio frame.In addition, supposing that last the second time slot district in the some subframes that form message X is designated as carries out the carrier sense operation.
Figure 19 illustrates the figure with another example of carrying out the carrier sense operation according to the configuration given zone of third embodiment of the invention.Especially, in Figure 19, suppose eNB(or UE) supposition that uplink/downlink sub-frame configuration based in part T is repeatedly applied from the first subframe of radio frame #0, only in being designated as the corresponding district (the last subframe corresponding with part T is the second time slot district of SF#n) that carries out the carrier sense operation, with respect to unwarranted frequency band, carry out the carrier sense operation.In addition, in Figure 19, suppose that the uplink/downlink subframe of message X is configured to [DDDUDUDDDD] by the mode with identical in Figure 18.
With reference to Figure 19, determining that eNB is the result of carrying out the carrier sense operation with respect to unwarranted frequency band in the second time slot district of SF#n while being idle duration " T_IDLE " in the last subframe corresponding to part T, eNB can be from SF# (n+1) be SF# (n+1) to the unwarranted frequency band of use during SF# (N+T) at part T.Although supposition T_IDLE is the length of a time slot (=0.5ms), T_IDLE can be set to other value.The T_IDLE value can be predetermined value shared between eNB and UE, or eNB can notify this T_IDLE value to UE by high-level signaling more.
Figure 20 illustrates the figure with the another example of carrying out the carrier sense operation according to the configuration given zone of third embodiment of the invention.In Figure 20, suppose equally eNB(or UE) supposition of repeatedly being applied from the first subframe of radio frame #0 of uplink/downlink sub-frame configuration based in part T only carries out the carrier sense operation with respect to unwarranted frequency band during being designated as the corresponding district (the last subframe corresponding with part T is the second time slot district of SF#n) that carries out the carrier sense operation.In addition, in Figure 20, suppose that the uplink/downlink subframe of message X is configured to [DDDUDUDDDD] in the mode with identical in Figure 19.
With reference to Figure 20, determining that eNB is that the result of carrying out the carrier sense operation with respect to unwarranted frequency band in the second time slot district of SF#n is busy in the last subframe corresponding to part T, eNB can be that SF# (n+1) is to SF# (n+T) at part T(from SF# (n+1)) during do not use unwarranted frequency band.Although supposition T_IDLE is the length of a time slot (=0.5ms), T_IDLE can be set to other value.The T_IDLE value can be predetermined value shared between eNB and UE, or eNB can notify this T_IDLE value to UE by high-level signaling (or physical layer signaling) more.
The<the four embodiment >
Therein in the situation by unwarranted frequency band application carrier aggregation technology, if the configuration of uplink/downlink subframe is dynamically altered with respect to unwarranted frequency band, can be as not default up link license transmission time (or downlink allocation information transmission time) and up link license time of reception and the relation (or downlink allocation information time of reception and PDSCH relation transmission time between) of PUSCH between the transmission time in routine techniques.
In this case, eNB can send to UE by the up link license at the SF#n place, and then at SF#k(k >=(n+4) wherein) locate the additional up link license enable messages that is used for enabling the up link license is sent to UE, make UE the up link based on before having received to permit to carry out ul transmissions (being the PUSCH transmission).Alternatively, eNB can send to UE by descending connected link assignment information at the SF#n place, and then at SF#k(wherein k >=n or k > n)) locate the additional downlink allocation enable messages that is used for enabling downlink allocation information is sent to UE, make UE can the downlink allocation information based on before having received carry out down link data and receive (being that PUSCH receives).
Time when eNB permits that by up link enable messages sends to UE can be for SF# (n+4) or at SF# (n+4) available SF#k(k wherein afterwards > (n+4)).In addition, receive the UE execution uplink data transmission of up link license enable messages from eNB at the SF#k place when, the time that is PUSCH when transmission can be and identical time, i.e. SF#k or receive the very first time SF# (k+1) of up link after permitting the SF#k of enable messages at it when up link license enable messages is received.
PUSCH transmission therein permits the very first time SF# (k+1) after the SF#k of enable messages to locate to be performed in the situation that it receives up link, and up link license enable messages is sent to its downlink subframe can use subframe or the special subframe had such as the short length of DwPTS.As UE at propagation delay (T p) be present under the condition between eNB and UE while carrying out the PUSCH transmission, can guarantee to be employed T APUSCH transmission.In this method, eNB can implicitly notify UE SF# (k+1) to be used to the UL subframe.Locate in corresponding UL subframe (being SF# (k+1)), can not send use leading of this subframe of indication.
Simultaneously, do not use the last symbol of downlink subframe or the DL subframe of one or more symbols can be defined as short DL subframe.If T pBe present between eNB and UE when the subframe after short downlink subframe is used as uplink sub-frames, so short downlink subframe can be set to guarantee the T of uplink sub-frames A.In addition, short downlink subframe can be used as the means of uplink sub-frames for implicitly notify the short downlink subframe of UE subframe afterwards for eNB.At corresponding UL subframe place, can not send use leading of this subframe of indication.In addition, used therein in the situation of short downlink subframe, UE UE therein changes T by the subframe interface from the uplink sub-frames after short downlink subframe AState under operate.
Figure 21 is the figure illustrated according to the example of the short downlink subframe of application of fourth embodiment of the invention.Especially, in Figure 21, short downlink subframe is configured to not use the last symbol of general downlink subframe, and the subframe of supposition after short downlink subframe implicitly is used as uplink sub-frames.In addition, suppose the uplink sub-frames place after short downlink subframe, do not send use leading of the corresponding subframe of indication.
Can realize as follows interlocking (interlock) relation between the PUSCH transmission of permitting based on up link and the PUSCH transmission of permitting enable messages based on up link.
At first, be selected from certain number aim sequence among the sequence of N altogether that can be used as leading (sequence of being identified by eNB and UE) and can be used as subframe leading that up link license transmission and up link are permitted enable messages.For example, sequence B based on being selected from the certain number aim sequence is used as the leading supposition that the up link license is sent to its SF#x, if the up link enable messages is at SF#y(y >=(x+4) wherein) locate to be sent to the leading sequence B that is used as SF#x, the up link that UE locates the SF#x based on received at SF#y or SF# (y+1) permits to carry out the PUSCH transmission.
Otherwise the index information of the downlink subframe that up link license has been sent to can be included in sequence, be used as subframe leading that up link license transmission and up link are permitted enable messages.Therefore, the up link of UE based on receiving permits to carry out the PUSCH transmission, at the corresponding index information of downlink subframe place based on downlink subframe, receives the up link license that this receives.
About the information of the sequence among the leading sequence of N altogether that is selected from the subframe that is used as up link license transmission and up link license enable messages can be by sharing and be configured between eNB and UE.
In addition, as the result of " to the competition of medium access " in unwarranted frequency band, the starting point enabled of the previous UL license sent and base PUSCH transmission thereon can be variable, unlike in the subframe interface, is fixing.Especially, wherein up link license enable messages uses situation about sending with leading identical structure corresponding to this situation in unwarranted frequency band.Except PUSCH as above transmission, as the result of " to the competition of medium access " in unwarranted frequency band, the starting point of PDSCH transmission can be variable, unlike in the subframe interface for fixing.
Figure 22 illustrates particular sequence to be used as to the figure of leading example that permits the subframe of enable messages for up link license transmission and up link according to fourth embodiment of the invention.Especially, this particular sequence is expressed as sequence B.
With reference to Figure 22, can see, although UE has received the up link license at the SF#x place from eNB, the up link license that in fact PUSCH locates based on SF#x at SF# (x+7) according to up link license enable messages is sent out.
In addition, indicate the subframe index information of a plurality of additional sub-frames or number of subframes counter can as described above, be included in up link license (or the subframe of transmitting for the up link license is leading) and up link license enable messages.For example, if eNB therein N subframe index be included in wherein and with the subframe index of before by up link, having permitted (or for the subframe of up link license transmission leading) to send (for example, in N subframe index one) identical index is included under the state in the up link license enable messages sent subsequently up link license (or for the subframe of up link license transmission leading) is sent to UE, UE can be when receiving corresponding up link license enable messages and be SF#w or the up link of locating based on before having received at follow-up time SF# (w+1) permit to carry out the PUSCH transmission.
The<the five embodiment >
In the wireless communication system of having applied carrier aggregation technology, the principal component carrier wave across the auxiliary component carrier of carrier dispatching (for example, in the situation of a plurality of PUSCH transmission unwarranted frequency band), the downlink subframe by the principal component carrier wave is the information that up link license that PDCCH sends can not comprise relevant (auxiliary component carrier) a plurality of subframe index.That is to say, with previous up link, permit the corresponding subframe index information of downlink subframe of the principal component carrier wave that has been sent to it can be included in up link license enable messages, make the up link of UE based on before having received permit to carry out a plurality of PUSCH transmission of auxiliary component carrier.
In addition, when determining that the result of eNB with respect to the operation of the execution of the auxiliary component carrier (CC#2) in unwarranted frequency band carrier sense is the free time, eNB can be used CC#2 during the transmission opportunity that comprises N SF (TxOP) part.ENB can be in advance for example, by more high-level signaling or physical layer signaling (, the down link principal component carrier wave in authorized frequency bands) are notified the use of N value and N subframe to UE.
In addition, eNB can will specify leading (or sequence) for this use to send to UE by the CC#2 in unwarranted frequency band in advance, in order to notify the information of the starting point of relevant TxOP to UE.The information of the use of relevant N value (being the length of TxOP) or N SF can be sent out under the state be included in leading.After leading being sent out, if under the state that eNB is complementary at the subframe interface with the LTE-A system, actual downlink information is sent to UE, the sequential gap may reside in preamble transmission time and downlink information between the transmission time.Especially, CC#2 can not be used exclusively by corresponding eNB and UE, and be based on carrier sense, uses by competing.During such sequential gap, another system can be attempted communication.
In order to prevent that another system from attempting communication during the sequential gap, therefore, eNB can send by the CC#2 of unwarranted frequency band carrier wave and retain transmission block (CRTB).CRTB means to be sent out to retain a kind of falseness (dummy) information of copy of the part of CC#2 or PUSCH.Can be during this sequential gap (for example in preamble transmission time and actual downlink information between the transmission time) send CRTB.
Exceptionally, the first subframe of TxOP part is arranged in the situation of up-link information transmission therein, and above-described CRTB can be sent out the time corresponding with (the Rx-Tx switching time of actual when transfer of data Jian – eNB) after preamble transmission completes.
Figure 23 is the figure illustrated according to the example of using auxiliary component carrier during comprising the TxOP part of N subframe of fifth embodiment of the invention.
With reference to Figure 23, when determining that the result of eNB with respect to the auxiliary component carrier CC#2 execution carrier sense operation in unwarranted frequency band is the free time, eNB can be used CC#2 during comprising the TxOP part of N SF.In this case, suppose eNB in advance by high-level signaling more to UE notice N value be set to 6 and SF be set to the use of [DDUDUD].
Under the condition of UE at Figure 23 according to receiving from eNB across the SF#n place of carrier dispatching principal component carrier wave CC#1 in authorized frequency bands by PDCCH while permitting with respect to the up link of the CC#2 unwarranted frequency band, therein with the PUSCH transmission of corresponding up link license interlocking in the situation that be performed in the TxOP part, the up link license enable messages that eNB will not be used for enabling corresponding up link license sends to UE.In addition, in this case, UE does not expect to receive for enabling the up link license enable messages of corresponding up link license from eNB yet, and locates to permit to carry out the PUSCH transmission based on up link in the PUSCH transmission time (being UL SF# (n+k)) with up link license time of reception (being DL SF#n) interlocking.Can according to pre-defined rule, (for example, k=4) use the PUSCH transmission time (being UL SF# (n+k)) interlocked with up link license time of reception (that is, DL SF#n).
Under another pattern, with PUSCH transmission time (being UL SF# (n+k)) of up link license time of reception (being DL SF#n) interlocking, may be defined as and follow the nearest up link of the next one that comprises SF# (n+4) and can use subframe.Can making in predetermined TxOP part permit for changing with up link the PUSCH transmission time (being UL SF# (n+k)) that time of reception (being DL SF#n) interlocks according to N SF.In addition, above-described up link license enable messages can for the sequence of before being appointed as such use leading (for example, send to the CC#2 arranged as the down link component carrier in unwarranted frequency band) or the value (for example, sending to the CC#1 arranged as the down link component carrier in authorized frequency bands) of the specific fields that sends by physical control channel.
On the other hand, as UE according to receiving from eNB across the SF#n place of carrier dispatching principal component carrier wave CC#1 in authorized frequency bands by PDCCH while permitting with respect to the up link of the CC#2 unwarranted frequency band, therein with the PUSCH transmission of corresponding up link license interlocking in the situation that be performed outside the TxOP part, eNB can send to UE by the up link license enable messages that is used for enabling corresponding up link license.In addition, in this case, UE also expects to receive from eNB the up link license enable messages that is used for enabling corresponding up link license, and, when receiving up link license enable messages, the PUSCH transmission is carried out in the up link license (PDCCH received at SF#n) based on before having received.
Figure 24 is the figure illustrated according to the example of the execution PUSCH of fifth embodiment of the invention transmission.Especially, in Figure 24, suppose N be set to 6 and the use of SF be set to [DDUDUD] by the mode with identical in Figure 23.In addition, suppose that UE locates to receive the up link license with respect to the CC#2 unwarranted frequency band from eNB according to DL SF# (n+l), DL SF# (n+4) across carrier dispatching CC#1 in authorized frequency bands and DL SF# (n+11).
With reference to Figure 24, in the TxOP part, at UL SF# (n+5), locate to hold the PUSCH transmission row of permitting interlocking with the up link of DL SF# (n+l).Therefore, the additional up link license enable messages that eNB will not locate to receive at DL SF# (n+1) is used for enabling the up link license sends to UE.In an identical manner, at UL SF# (n+15), locate to carry out the PUSCH transmission of permitting interlocking with the up link of DL SF# (n+11) in the TxOP part.Therefore, the additional up link license enable messages that eNB will not locate to receive at DL SF# (n+11) is used for enabling the up link license sends to UE.
On the other hand, eNB locates rather than enables in corresponding TxOP part in the situation that DL SF# (n+4) locates the up link license sent at UL SF# (n+13) therein, and eNB locates to permit the up link license enable messages of (being DL SF# (n+4)) to send to UE by being used for enabling corresponding up link at DL SF# (n+12).
In this case, suppose that up link license enable messages comprises the downlink subframe index information particularly, the up link license enabled by eNB is sent to this downlink subframe index information.For example, the up link license enable messages of locating to send at DL SF# (n+12) comprises the downlink subframe index information of DL SF# (n+4).Therefore, UE locates to enable at UL SF# (n+13) the up link license of before having located to receive at DL SF# (n+4).
In other method, eNB and UE can implicitly arrange current up link license enable messages, make up link license enable messages before deserving enable to have the up link license of transmission/reception time the earliest.In addition, eNB and UE can implicitly be arranged on the up link license enable messages that DL SF#n place receives, and make the up link license enable messages received at DL SF#n place enable the up link license received at the previous nearest DL SF place that comprises DL SF# (n-4).
In another method, in the situation that the ul transmissions by CC#2 is performed based on asynchronous HARQ therein, up link license enable messages can comprise (up link) HARQ ID enabled by eNB.For example, the HARQ id information of UE based on comprising in up link license enable messages carried out the re-transmission of previous ul transmissions (for example, identical (up link) HARQ ID).In addition, the re-transmission that may be limited to the initial uplink transmission of carrying out in the TxOP part makes when correspondence system reuses CC#2, this re-transmissions with (in TxOP) executed wherein in the identical uplink sub-frames of the subframe transmitted of initial uplink, be performed.That is to say, in Figure 24, can locate to carry out at UL SF# (n+15) re-transmission of UL SF# (n+5).
Said method can be widely applicable for wherein UE and receive the situation with respect to the up link license of CC#2 according to the particular physical channel of dispatching by CC#2 from eNB.The time when particular physical channel by CC#2 receives the up link license with respect to CC#2 from eNB according to scheduling as UE can be to determine the time when with respect to CC#2, carrying out result that carrier sense operates and be the free time as eNB.
The<the six embodiment >
ENB determines that the result that UE carries out the carrier sense operation with respect to the CC#2 in unwarranted frequency band is idle therein, and arrange in the situation of the TxOP that comprises N SF, all SF that form a specific T xOP can be arranged to downlink transmission or uplink data transmission.This method has advantages of the number that can be minimized in the special SF generated in a specific T xOP.
In addition, only for the length (being N_DL) of the TxOP of DL transfer of data with only for the length (being N_UL) of the TxOP of UL transfer of data, can be provided as and be equal to each other or differ from one another.In one embodiment, eNB can notify the length of TxOP by the more high-level signaling by the principal component carrier wave in authorized frequency bands or its physical channel to UE.Alternatively, eNB can be included in the information of the use of the length by about TxOP and TxOP under the state in leading (or sequence) of the starting point that is designated as the TxOP that notice sends by the CC#2 in unwarranted frequency band the information of the use of the length about TxOP and TxOP is sent to UE.In addition, eNB can be notified the use of specific T xOP by the physical channel by the principal component carrier wave (CC#1) in authorized frequency bands before applying practically at TxOP to UE.Alternatively, the use of specific T xOP can sequentially be set according to the predetermined service regeulations (sequence) of TxOP.
Hereinafter, all frames that form for convenience of description TxOP will mean by " TxOP_DL " and " TxOP_UL " respectively, and the use of this TxOP is arranged to downlink transmission and uplink data transmission.
Figure 25 is the figure illustrated according to the example of the configuration TxOP of sixth embodiment of the invention.Especially, in Figure 25, suppose that eNB comprises under the state during (sheltering) before is being designated as leading (or sequence) of starting point of notice TxOP the information of the use of the length about TxOP and TxOP is sent to UE in the information of the use of the length by about TxOP and TxOP.
With reference to Figure 25, the use at first arranged of TxOP and the length (being N_DL) at first arranged are designated as respectively downlink transmission (being TxOP_DL) and 5, and the use secondly arranged of TxOP and the length (being N_DL) of next setting are designated as respectively uplink data transmission (being TxOP_UL) and 3.
After leading being sent out of the starting point that is used for notifying TxOP, if actual transfer of data is configured to carry out according to the subframe interface of LTE-A system, the sequential gap may reside between preamble transmission time and actual data transmission period.In this case, eNB also sends CRTB in order to prevent that another system from attempting transfer of data during the sequential gap.
Under the condition of UE at Figure 25 during according to the up link license that receives from eNB across the SF#n place of carrier dispatching principal component carrier wave CC#1 in authorized frequency bands by PDCCH with respect to the CC#2 unwarranted frequency band, UE can with reference at corresponding time SF#n place, arrange virtual the time sequence index (virtual timing index) (VTI) carry out the PUSCH interlocked with the up link license and transmit.Below propose to be widely applicable for wherein eNB and will permit the situation that send to UE with respect to the UL of CC#2 by specific physical control channel or the physical data channel of CC#2.
Therein UE according to across carrier dispatching in the situation that the special time receiving uplink of TxOP_DL license, VTI refers to that being shown in this sequential must be TxOP_UL at the follow-up TxOP(that is provided for the UL transfer of data) locate to send the parameter of PUSCH.For example, UE is according to across carrier dispatching, in the license of the DL of TxOP_DL SF#n place receiving uplink and in the situation that the VTI of DLSF#n is set to 1, UE, in the first up link of uplink sub-frames place based on DL SF#n of follow-up TxOP_DL, permitting to carry out the PUSCH transmission therein.
Therefore, VTI is different from and means up link time of reception and the poor existing parameter of the absolute time of PUSCH between the transmission time, and can very effectively be applied in the situation by unwarranted frequency band application carrier aggregation technology, guarantee that in this unwarranted frequency band fixedly the PUSCH transmission time is difficult.
In addition, the reference point of VTI can implicitly be assumed to the first uplink sub-frames of TxOP_UL, or can be by more high-level signaling or physical channel are specified particularly.
1) eNB can be included in the information of the VTI by relevant every downlink subframe under the leading state of the starting point that is sent out to notify TxOP or to send to UE(by previous appointment for the leading information by the VTI of relevant every downlink subframe of the transmission of VTI information be semi-static technique).In this method, when being set up, TxOP can reassign the information of the VTI of relevant every downlink subframe.ENB can the transfer of data by TxOP by before carrying out practically by the physical channel of CC#1 or CC#2 or more high-level signaling to the information of the VTI of the relevant every downlink subframe of UE notice.
2) alternatively, eNB can by the physical channel of CC#1 or CC#2 or more high-level signaling the information of the VTI of relevant every downlink subframe is sent to UE, or the information (being static technique) of the VTI of relevant every downlink subframe can be set according to predetermined VTI allocation rule.Although TxOP sets and is repeated, the method can be used to the time period that the Information preservation of the VTI of relevant every downlink subframe is relatively long in fixed value.
The maximum of TxOP_DL arranges in the situation that length is defined as N_DL_MAX therein, before eNB can be provided so that at the length-specific of TxOP_DL to be maintained at fixed value for long-time section VTI information, by high-level signaling more, notifies the VTI information of relevant N_DL_MAX DL SF to UE.
In addition, in the VTI allocation rule, can implicitly suppose that VTI is distributed from the DL SF of set TxOP_DL by the ascending order with power.The method does not require additional signaling.
In another example of VTI allocation rule, only, therein in the situation that any DL SF place is used CCS to receive the up link license, can implicitly suppose the VTI about DL SF with the ascending order of power.
3) in another method, therein eNB by across carrier dispatching in the situation that any downlink subframe place will send to UE with respect to the license of the up link of CC#2, eNB can by the physical channel of CC#1 or CC#2 or more high-level signaling to the VTI(of the relevant corresponding downlink subframe of UE notice, be dynamic technique).
In semi-static technique as above, static technique and dynamic technique, when eNB notifies the VTI information of every downlink subframe by the physical channel of CC#1 or CC#2 to UE, for the field that realizes this, can again be added to the existing down link control information (DCI) transmitted for the up link license or can be defined in addition new DCI.In addition, eNB can be by the previous leading VTI information from every downlink subframe to UE that notify of definition for this purpose.
In addition, in semi-static technique, static technique and dynamic technique, the VTI of some downlink subframe (for example can be set to predetermined value, 0 or negative integer) with notice by not yet receive up link license at corresponding downlink subframe place across carrier dispatching, although perhaps, by receive the up link license across carrier dispatching, be not performed with the PUSCH transmission of this up link license interlocking.
Alternatively, VTI can be defined as the parameter of the up link license that indication UE must receive with reference to the sequential place in the previous TxOP_DL part arranged so that at the special time place of TxOP_UL transmission PUSCH.For example, UE carries out the PUSCH transmission in the situation that have the UL SF place of the TxOP_UL of the VTI that is set to 1 therein, and UE is with reference to the up link license finally received in the previous TxOP_DL part arranged.
Figure 26 is the figure illustrated according to the example of the execution PUSCH of sixth embodiment of the invention transmission.Especially, in Figure 26, suppose that eNB locates the license of the up link with respect to CC#2 is sent to UE at the SF# of CC#1 (n+l), SF# (n+3) and SF# (n+4) across carrier dispatching with the basis of the mode with identical in Figure 25.In addition, in Figure 26, suppose that eNB is included under the state in the starting point that is sent out to notify TxOP leading the information of the VTI of relevant every downlink subframe is sent to UE in the information of the VTI by relevant every downlink subframe.
With reference to Figure 26, therein in the situation that the VTI that SF# (n+l), SF# (n+3) by having received up link license across carrier dispatching and SF# (n+4) locate is set to respectively 1,2 and 3, the first uplink sub-frames that the PUSCH of the up link license based on by locating to receive at the SF# of TxOP_DL (n+l), SF# (n+3) and SF# (n+4) across carrier dispatching transmits respectively at TxOP_UL is that SF# (n+10), the second uplink sub-frames are that SF# (n+11) and the 3rd uplink sub-frames are that SF# (n+12) locates to be performed.
